MOP-WRINGER.

SPECIFICATION forming part of Letters Patent No. 512,795, dated January16, 1894.

Application filed January 21, 1893. Serial No. 459,081. (ModeL) To allwhom it may concern:

Be it known that 1, WILLIAM H. BETTS, a citizen of the United States,residing at Lincoln, in the county of Lancaster and State of Nebraska,have invented a new and useful Mop-Wringer, of which the following is aspecification.

My invention relates to improvements in mop wringers that are attachedto a pail or other vessel for holding water and in which the pressureupon the mop is obtained from springs acting upon one of the rollerswhich is movable; and the objects of my improvement are, first, toprovide a spring that will adjust itself to any unequal pressure on thetwo ends of the roller, and second, to provide for releasing the springso that the rollers may be readily separated for the insertion of themop. I attain these objects by the mechanism illustrated in theaccompanying drawings in Which- Figure 1 is a vertical section of a moppail with my improved wringer attached. Fig. 2 is a top view of thesame.

Similar letters refer to like parts throughout.

The roller frame H is secured to the pail A by clips in each of which isa set screw 2'. One of these clips is attached to the frame H and theothers to the lugsc 0. These lugs are bolted to the frame at it, thebolts passing through a slot in the frame H which allows them to beadjusted to the width or shape of the pail. The roller b revolves uponjournals having fixed bearings in the frame H, while the journals of theadjustable roller 1) work in slots in the frame H which allow saidroller to be drawn back to the position shown in dotted lines at b". Therequisite pressure upon the roller b is given, by the spring S the twoends of which are attached to the journals of the roller, while thecenter is held in place by the knee is which is secured for that purposeto the frame H. On the center of the spring S I have placeda frictionroller 1' which bears against the knee is and, is useful in securing orreleasing the spring. By using a single spring made in this form andattached to both ends of the roller an equal pressure is exerted ateither end, the roller adjusting itself to the uneven thickness of themop.

In operation the spring S is released and the roller b drawn back asindicated" in dotted lines at b" the friction roller 7'" then lying uponthe inclined part of the knee is as shown at 7*. 'After inserting themop between the rollers, the roller b is moved up by pressing upon thespring S at the point of attachment of the friction roller 4" whichfollows down the inclined part of the knee is until it reaches that partwhich is perpendicular to the plane of movement of the roller 1) whichis then permanently locked in position.

"A foot rest G is attached to the pail for convenience in holding itwhile the mop is being drawn through the rollers.

Having thus fully described my invention, I claim 1. In a mop Wringerthe spring S attached at the two ends of the adjustable roller b andhaving a central bearing on the knee is from which it may be released inorder to separate specified.
